Instructions
Slice the beef thinly. Any tender cut like sirloin, ribeye, etc., works well—but note, this recipe uses beef chuck roast, a cheaper cut. I'll show you how to marinade and cook it to make it tender and juicy like restaurant-quality meat.
Marinade the beef with 2 teaspoons of soy sauce, 1 teaspoon grated garlic, 1 teaspoon grated ginger, 1/2 teaspoon salt, 1/2 teaspoon baking soda, and 1 teaspoon cornstarch. Mix well, cover, and let sit for at least 30 minutes.
While waiting, crush and dice 10 cloves of garlic. Yes, that's a lot, but it's why the dish is so flavorful.
Dice the key ingredient: 豆豉 (Douchi), also known as fermented and salted black soybeans. Its sharp, pungent aroma adds umami. Roughly chop and set aside with the garlic.
Prepare vegetables: halve a green bell pepper, a red bell pepper, add some carrot slices and onion slices. These colorful vegetables enhance the dish’s visual appeal.
Quickly make a sauce by mixing 1 tablespoon soy sauce, 1 tablespoon oyster sauce, a dash of white pepper to taste, and 1 cup beef stock. Stir well.
Heat your wok until slightly smoking. Add about 2.5 tablespoons oil and swirl to coat the bottom. Add the beef in a single layer. Let it sear on one side until lightly charred, then stir-fry to cook the other side. Continue until you see nice charring on the edges, then remove the beef. Tilt the wok to let excess grease remain behind.
With about 2 teaspoons oil remaining and crispy bits on the wok bottom, do not wash the wok. Add a bit more oil if needed and sauté the garlic and black beans at low heat until fragrant.
Add all prepared vegetables to the wok. Stir-fry until they begin to soften. Then pour in the sauce to deglaze, scraping up all the flavorful bits. Once the sauce is bubbling, taste and adjust seasoning if necessary. Add cornstarch water (2 teaspoons cornstarch mixed with 1 tablespoon water) and stir quickly to thicken the sauce.
Return the beef to the wok. Mix everything until well combined and serve.
